I have read the material on how to do this but I’m stuck trying to figureout how to pass a parameter to my JavaFX2 application with in browser mode or webstart mode.
I’ve asked the question on OTN forums also here

So I imported ColorfulCircles project from the Ensemble into Netbeans. Then I modified the code and put in a small snippet to pull a parameter after init method, like so. I just get the parameter and set it as title for the stage.

                @Override public void start(Stage primaryStage) throws Exception {
                init(primaryStage);

                Parameters params = getParameters();
                String myTitle = params.getNamed().get("myTitle");
                primaryStage.setTitle(myTitle);

                primaryStage.show();
                play();
                }

I then did a clean and build in netbeans…all html, jar, jnlp etc was generated.

I then manually modified the HTML as shown below. But the title for the stage doesnt update/show, for either modes.
What is missing here?
